Simulation of the robot
The robot is controlled to move video camera by remote incoming command of the user through internet.The servers programs are implemented with PHP server coding. The PHP interpreter uses the graphical library GD for extending the graphical functionality and to keep the interface for controlling the robot.

The image that is sent to the browser is a rectangle part of the image scene.png. The image scene.png is a picture of whole work scene.PHP uses the GD Library for most of the image functionality that it offers. GD is a library used for generating two-dimensional graphics.
Real Robot Control
Client sent command using HTML formApache server gets the requestPHP script opens serial port and send input the robotThe arduino controler read input data from serial port and control the drives.
Conclusion
This technological solution develpod has been applied for distance learning in robot control laboratory
